ABSTRACT OF THE DISCLOSURE A mixing valve for hot and cold domestic water has a control member movable within a body whereby axial movement of the control member controls opening and closing of communication from hot and cold inlets to an outlet and rotation of the control member controls the relative proportions of fluid flow from respective inlets to the outlet. A pressure chamber is supplied with pressure fluid from the inlets for assisting closing action of the valve upon closure of a vent from the pressure chamber. In order to resist pressure surges at either inlet a restricted aperture is provided to reduce flow from a reducing volume movement damping chamber towards the end of closing movement of the valve control member to prevent the final portion of the valve closing movement being too sudden.
